SPECIFICATION forming part of Letters Patent No. 790,733, dated May 23, 1905.

Application filed July 12, 1904. Serial No. 216,277.

T 0 (tZZ whom, it nan/y concern:

Be it known that we, JAMES A. LINN, residing at New Philadelphia, in the county of Tuscarawas, and J ACOB GEIB, residing at Steubenville, in the county of J elferson, State of Ohio, citizens of the United States,have invented new and useful Improvements in Oasters, of which the following is a specification.

Our invention relates to improvements in that class of devices known as casters.

Said invention or caster has for its object to provide for its ready and etl'ective application or attachment to the article or object in connection with which it is to be usedas, for instance, heavy boxes, more particularly cofiin rough-boxesfor conveniently moving them as in shipping the same, and which caster shall be readily detachable from such object or box.

Said invention is characterized for simplicity, lightness, yet being substantial, and cheapness of manufacture; and it consists of certain structural details substantially as hereinafter more fully disclosed, and particularly pointed out by the claims.

In the accompanying drawings, illustrating the preferred embodiment of our invention, Figure l is a plan view thereof. Fig. 2 is a View looking directly at the angle of the bracket or casting of the caster. Fig. 3 is a side view, and Fig. 4 is a vertical central section of the invention.

In the carrying out of our invention we produce a bracket or casting 1, preferably in general outline V shape in horizontal or crosssection and with an integral tubular extension or socket 1 at the angle resulting from such shape to receive the spindle 2 of the caster-Wheel 2, Within which socket said spindle is suitably and fixedly held, the divergent portions resulting from the peculiar or V form of the bracket or casting 1 or upstanding lateral wings or plates, adapted to embrace right-lined surfaces at right angles to each other, the angle formed on the latter being received within the reentrant angle of the former, the practical application of which will be apparent later. Said caster-wheel 2 has its axle or journal 52 hung or secured in a preferably malleable-metal stirrup or bearing 2, with the uniting portion between the arms of said stirrup looped, as at T, to form substantially an eye to receive said spindle and permit the swiveling action of said stirrup or bearing upon the latter. Said stirrup or bearing is suitably held as against vertical displacement by a collar 2*, located upon the spindle 2 in between the stirrup 2 and the bracket 1, and a ring or shoulder 2 upon said spindle arranged below said stirrup. Said bracket or casting 1 by reason of its abovenoted outline or contour is adapted, as will be observed, to snugly it directly upon the corner of the box or other like object with its upstanding divergent portions or wings engaging surfaces of the latter at right angles to each other. Said wings or divergent portions are provided with preferably countersunk openings 1 to receive screws or like fastenings to aid the securing of said bracket or casting in place upon the box-corner. Said bracket or casting has a transverse member 1 extending from the bottom edges of the wings thereof and at the most distant or divergent points therebetween to enable said transverse or horizontal member to take under the box. Said bottom member l has about at the center of its upper surface an upstanding pointed teat or penetrating-fastening 1, adapted to be readily driven into or penetrate the bottom of the box from the under side to further aid the securing of the caster loracket upon the latter. Said bracket or casting has, as it were, a lower portion of its angle removed or cut away along a line extending or curving from the lower end of the socket 1 downward and inward through the wings of said bracket, terminating at the bottom surface of said wings short distances from the inner vertical edges of the last named, producing an opening 1 in said bracket, initially receiving the bottom corner edge of the box. Said corner edge of the box, however, is removed or reduced sufficiently to take it out of the way of the swing or play of the caster wheel or roll, as when moving the box.

Latitude is allowed as to details herein, as

they may be changed as circumstances suggest without departing from the spirit of our invention.

We claim- 1. A caster comprising a frame or bracket having upstanding or plate-like divergent portions or wings adapted to embrace right-lined surfaces at right angles to each other, and having a spindle-receiving socket at their points of convergence standing beyond the plane of said bracket, said wings having their lower edges removed from the lower end of said socket downward and inward suitably to permit the play or swing of the caster-wheel carrying stirrup or bearing within the plane of said frame or bracket and outward from, and in a plane above the bottom edge of said bracket or frame.

2. A caster having its bracket formed with divergent wings and a spindle-receiving socket arranged at the convergent or meeting portions of said wings, said wings having their lower edges cut away or extending from the lower end of said socket inward and clownward suitably to permit the play or swing of the caster-wheel carrying stirrup or bearing within the plane of said bracket, said wings also having at their bottom divergent edges, a connecting-bar adapted to efi ect connection therebetween and the article to which the cas ter may be applied.

3. A caster having its bracket formed with divergent wings, and a spindle receiving socket arranged at the convergent or meeting portions of said wings, said wings having their lower edges cut away or extending from the lower end of said socket inward and downward suitably to permit the play or swing of the caster-wheel carrying stirrup or bearing within the plane of said bracket, said wings also having at their bottom divergent edges, a connecting-bar equipped with a penetrating teat or fastening.

In testimony whereofI have signed my name to this specification, at New Philadelphia, in the county of Tuscarawas and State of Ohio, this 28th day of June, 1904, in the presence of two subscribing witnesses.
